Detailed Description
A raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps.
It can be created from a raster file on device or from a raster function.
Supported Raster formats include:
- ASRP/USRP
- CIB1, 5, 10
- DTED0, 1, 2
- GeoTIFF
- HFA
- HRE
- IMG
- JPEG
- JPEG 2000
- NITF
- PNG
- RPF
- SRTM1, 2
- Mosaic Dataset in SQLite (read-only)
Learn more about rasters from the ArcGIS Desktop documentation.
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
| Type | Default Property |
|---|---|
| RasterFunction | rasterFunction |
See also Loadable, RasterLayer, and Loadable.
Property Documentation
[read-only] loadError : Error |
Returns the load error (read-only).
Note: load errors are also reported on the error property and emit the errorChanged signal.
See also Loadable.
[read-only] loadStatus : Enums.LoadStatus |
The Enums.LoadStatus of the Raster.
See also Loadable and Enums.LoadStatus.
path : url |
The path to the local raster image file.
Note: You cannot set the path to the raster after the instance is already loaded.
[default] rasterFunction : RasterFunction |
The raster function used to construct this Raster.
[read-only, since Esri.ArcGISRuntime 100.1] rasterType : Enums.RasterType |
Returns the Raster type (read-only).
This property was introduced in Esri.ArcGISRuntime 100.1.
See also Enums.RasterType.
Signal Documentation
loadErrorChanged() |
loadStatusChanged() |
Emitted when the loadStatus property changes.
Note: The corresponding handler is onLoadStatusChanged.
See also Loadable.
pathChanged() |
Emitted when the path property changes.
Note: The corresponding handler is onPathChanged.
rasterChanged() |
Emitted when the path or rasterFunction properties change.
Note: The corresponding handler is onRasterChanged.
rasterFunctionChanged() |
Emitted when the rasterFunction property changes.
Note: The corresponding handler is onRasterFunctionChanged.
